Not to mention the fact that it can do so in 1024pixels and at a photon resolution too. This means that it can actually capture snapshots of photons. While this is an achievement on its own, a huge one, the practical uses of this CMOS camera are far more exciting.

This camera can be used in a number of medical procedures to observe the human body at a level that was never possible before. It can lead to breakthroughs in DNA sequencing and push medical science to a whole new level.

The camera can actually photograph a photon on million times per second and give clearly visible photographs to the scientists who will then use it to understand things that happen in fractions of a second, like certain important chemical reactions.

This gives scientists a direct way of looking at things that are happening at a molecular level. That in turn enables them to see and understand minute things like how a particular drug is affecting our bodies.

It will have also have a decisive effect on almost all medical procedures that use visible light to scan areas. By observing reactions at molecular levels in great details, the technology will help pharmacologists to develop drugs that are better targeted and more effective. Ultimately, as a result of the enhanced understanding of DNA sequencing, we might finally achieve the goal of truly personalized drugs.

This camera would also enable scientists to study our neural structure at much greater detail, being able to actually see thoughts as they move along the neural channels as signals.

Besides the obvious possibilities to set a jumper or remove the bios battery to reset the bios password it is also possible to reveal or reset the bios password by using a software like CmosPwd which is available for Windows, DOS and Linux.

Most users will probably run the application in Windows. To do that they need to access the command line and install a driver that gives “direct port I/O access for specified ports to user-mode process (ring 3) using Ke386SetIoAccessMap and Ke386IoSetAccessProcess kernel functions.” The driver is located in the Windows directory of the software package after unzipping it to the computer.

The command ioperm.exe -i is used to install the driver which can be uninstalled with ioperm.exe -u after the bios password has been revealed. Once the driver is installed the bios password can be revealed with the command Cmospwd_win.exe which displays a list similar to the one below.

cmos password

The application requests the password for all known bioses. Only one hit will be found obviously which in the case of my bios was test in the Award 6.0 line. Reseting the bios can be initiated in DOS with the command cmospwd /k. Please note that the cmospwd.exe file is located in the DOS directory of the application. It can also be reset with the cmospwd_win /k in Windows.

Most notebooks store the bios password in an eeprom which can only be retrieved with an eeprom reader.

You have to enter the password to be able to access it, if you can’t provide the correct one the access gets denied. The following method describes a way to recover the password if you forgot it or bought a used computer with a bios password.

CmosPwd is a free program that is able to display information about the bios once it is executed. You do need to create a bootable disk to be able to execute the program in dos mode. To create a bootable disk in windows right-click the disk drive and select format from the list of options. It is important that you enable the option Create an MS-DOS startup disk.

Once the disk is created copy the contents from the dos folder of cmospwd to the disk and restart the computer. You will have to remove all hard drives from the system if you do not automatically boot from disk drive. Type cmospwd.exe in the command line and the password should appear. Ignore the information about the other bios manufacturers and take a look at the one your computer is using.

Another possible method would be to start the computer in safe mode with command prompt which could work as well. You still need to access the files somewhere so make sure that the hard drive is accessible.
